Titanic-sub Goes Missing and has Only 40 hours of Oxygen Left - US Coast Guard

A private submersible vessel carrying 5 people onboard to the visit to the Titanic wreck site goes missing after losing contact link with its mother ship. The titanic wreck is said to be lying roughly 4+kilometers below the surface of the ocean, and is said to be in the pitch dark region of the deep sea.

Finding the missing vessel is said to be as a task of finding a needle in an haystack, and given the time left for the rescue the chances are seemingly dim. Rushing to the rescue, US Coastguard says,

"A tourist submersible on a visit to the wreck of the Titanic with five people on board has just 40 hours of breathable air/oxygen left, after it was declared missing."

The search to locate the small, deep-diving vessel is ongoing after it lost contact while diving near the wreckage of the Titanic.

The research vessel Polar Prince lost contact with the crew of the Titan sub an hour and 45 minutes into its dive.

Tour firm OceanGate said it was exploring all options to get the crew back safely, and government agencies have joined the rescue with more international agencies rushing to the rescue.
